Sorry to follow up on this, but there’s a thread on the bug reports forum related to this issue as well. Besides the pet limit being reverted, we have had to re-train pet battling, multiple one-time quests have been reset, we cannot port to pet dungeons (via the Manapoof NPC), and the “Minion of Mayhem” title is gone.
Obviously the issue is known and being investigated, but those of us with accounts that are already affected have been submitting tickets, as directed here and by the support article. Presumably a bug fix alone will not also get our accounts back to where they were. Unfortunately, GMs so far seem to either be unaware of the issue, or unable to fix our accounts. The most recent response was to just point us to submit a bug report (see below).
So I’m just posting here to follow up and make sure that we should still be submitting tickets for this issue, and to perhaps help get the resolution for those of us affected properly communicated to the GMs that will need to help us.
Thanks!
